Potato Protein Power

If you have read one or many nutrition articles of recent years you would be forgiven for thinking that potatoes are nothing but carbohydrates with no other purpose as a food than converting to sugar, spiking blood glucose and creating havoc to our metabolic systems. Once a proud staple food, it has been attacked by dieters and professors alike, even relegated to the top tier (use sparingly) in an alternative Healthy Eating Pyramid.

You would also be forgiven for thinking of other foods, usually animal foods, as protein.

In food guides, foods are placed into various groups of similar nutrient value and these are usually fruit, vegetables, cereals, dairy and then a fifth group often named ‘protein‘ foods. Here ‘protein’ foods refer to meat, eggs, fish, poultry, legumes and nuts. The UK Eatwell Guide (1), although listing examples, refers to this group as ‘proteins’; the US Dietary Guidelines (2) refers to this group as ‘protein’ and ‘protein foods’; and the US Choose MyPlate as ‘protein’ (3). I note the Australian Dietary Guidelines (4) do not refer to this food group as ‘protein’ but rather lists the foods within the group ie: meat, poultry, fish, egg, tofu, nuts, seeds, legumes/beans. The Australian example aside, such messages of ‘protein’ as a food group from nutrition authorities in the UK and US, has a flow-down effect to health professionals and the public and this theme of ‘protein’ as a food group is common in the lay-press. One could mistakenly assume that those foods (meat, eggs, fish, poultry, legumes, nuts) are solely or predominantly protein; and that cereals, grains, tubers, potatoes, vegetables and dairy foods (which appear in different food groups) are thus low, inferior or poor quality sources of protein. Neither assumption is correct. Continue reading “Potato Protein Power”

A false dichotomy – dietary guidelines and the other diet

Dichotomy (2)
A Dichotomy – Black or White.

A dichotomy is a division into two entirely different and often contrasting domains, interests or activities (1). Examples of true dichotomies are black or white. Tall or short.

A false dichotomy is an argument giving a false illusion of there being only two choices whereas in reality there can be at least one other or even many possibilities (2). The argument is set up in such a way as the first choice is eliminated due to it being seen as a terrible choice, and the only other alternative is the second choice.

Over the last decade dietary guidelines have come under attack. Arguments against them are often presented in the manner of a false dichotomy. These are the steps used in that line of fallacy: Continue reading “A false dichotomy – dietary guidelines and the other diet”

Ultra-processed food (2)

Within two generations there has been a complete restructure of our food environments from mainly fresh foods prepared in the home, eaten with family or friends at the table with plates and utensils; to a high proportion of fast food, convenience food, snack-food, confectionery; from or at restaurants, cafes, take-away outlets and food-halls; out of bags, packets, bottles, cans, tubes, tubs … and eaten on the run.

Food History # 9 – ‘Please can you help?’ – Nutrition Studies 1991

After dramatic improvements in my son, I was inundated with queries from people wanting to try the Royal Prince Alfred Hospital exclusion diet for a range of symptoms. While I was pleased to help, I was concerned I did not have the required expertise to assist. I therefore studied for a Graduate Diploma of Human Nutrition, completed in 1991 through Deakin University. Continue reading “Food History # 9 – ‘Please can you help?’ – Nutrition Studies 1991”

Mid 1980s – A turnaround in my diet to Friendly Food

Sorting out the family diet after the RPAH protocol for food sensitivities (1) was at first daunting and confusing. The prime objectives were to get my son well, establish his symptoms due to diet and the culprit foods, then exclude only those foods. This final modified diet was to become the ‘friendly’ diet (2) we grew to know, of foods that were safe for my son to eat without him becoming ill. However, I also wanted the family diet to be a ‘healthy’ diet in fulfilling long-term objectives of preventing diseases that plagued my parent’s generation: heart disease, obesity and type 2 diabetes. The longer-term family diet also had to be nutritionally adequate, palatable, fit in with the family lifestyle and be socially acceptable. How could I meet all those objectives?  Continue reading “My food history # 8 – The 1980s Healthy Eating (Core Foods) Pyramid”
